Add a new kernel option RESTARTABLE_PANICS. If this option is present,
then one can restart from a panic by resetting the panicstr variable to
NULL. This commit conditionalizes the previously committed functionality
on this variable. It also removes the __dead2 attribute from the panic()
function so that when one continues from a panic() the behavior will
be predictable.
